Just curious if there is any way to get a /56 or /48 delegation instead of a /64 which does not ipv6 vlans. A /48 is recommended with a /56 considered the minimum any ISP should provide. If not this may push me to switch providers. Remember, ipv6 is infinitely large and is projected to last for 40 years minimum. It is like pre 1990s with ipv4 all over again and an ISP should not be stingy with IP address allotment.

C'mon quit bumping this. Nobody here has any influence on this. Plus if it's like the FTTN service AT&T is giving you half a /60 and how is that not enough for one house?

They might give a /61 prefix to the AT&T gateway, but when I tried setting up DHCPv6-PD on my own router sitting behind the gateway (with the gateway in "IP Passthrough" mode), I was only able to get a /64.

According to this post on AT&T's forums, the RG gets a /60 prefix, and then will hand out up to 8 /64 prefixes to DHCPv6-PD clients sitting behind it. In theory you could perhaps request multiple /64 prefixes, but my router doesn't support that configuration.
